1. Using a modeling knife, cut one length of silicon fuel
line (the length of silicon fuel line is calculated by
how the weighted clunk should rest about 5mm
away from the rear of the tank and move freely
inside the tank). Connect one end of the line to the
weighted clunk and the other end to the nylon pick
up tube in the stopper.
2. Carefully bend the second nylon tube up at a 45
degree angle (using a cigarette lighter). This tube
will be the vent tube to the muffler.
3. Carefully bend the third nylon tube down at a 45
degree angle (using a cigarette lighter). This tube
will be vent tube to the fueling valve.
When the stopper assembly is installed in the tank,
the top of the vent tube should rest just below the
top surface of the tank. It should not touch the top of
the tank.
4. Test fit the stopper assembly into the tank. It may be
necessary to remove some of the flashing around
the tank opening using a modeling knife. If flashing
is present, make sure none of it falls into the tank.
!
5. When satisfied with the alignment of the stopper
assembly tighten the 3mm x 20mm machine
screw until the rubber stopper expands and
seals the tank opening. Do not over tighten the
assembly as this could cause the tank to split.
6. Using a modeling knife, cut 3 lengths of fuel line .
Connect 2 lines to the 2 vent tubes and 1 line to
the fuel pickup tube in the stopper.
7. Feed three lines through the fuel tank
compartment and through the pre-drilled hole in
the firewall. Pull the lines out from behind the
engine, while guiding the fuel tank into place.
Push the fuel tank as far forward as possible, the
front of the tank should just about touch the back
of the firewall.
Blow through one of the lines to ensure the fuel
lines have not become kinked inside the fuel
tank compartment. Air should flow through easily.
Do not secure the tank into place permanently
until after balancing the airplane. You may need
to remove the tank to mount the battery in the
fuel tank compartment.
8. Secure the fuel tank.
